Case Mate has a product line called Clear Armor, its an invisible skin/case made of defense grade 3M film that was used for the military. Take a look at the clip below to see the level of protection it offers as they put two BlackBerrys (with and without Clear Armor) into an industrial grade Blendtec blender. This magical film actually withstood the abuse of the the legendary blender.
After watching this clip, I am sold on how tough these defense grade 3M protective films are. From the looks of it, it offers a transparent 360 degree protection for your iPod, iPhone or BlackBerry. It offers protection and good looks, a rare find! (source: Gizmodo)
